COTTON-CHOPPER.

Specification of Letters Patent.

Patented June 29; 1909.

Application led September -12, 1907. Serial No. 292,613.

' Cotton-Choppers, of which the following is a specification.

Our invention relates to an improvement in cotton choppers, andtheobject is to arrange the disks or blades so that all the surplus plantswill be removed or cut down,

and the standing plants left at predeterv mined intervals apart.

The invention relates to certainother novel features-of construction andcombinations of parts which'will be hereinafter describedand pointed outin the claims.

In the accompanying drawings, Figure 1 is a perspective view, Flg. 2 isa fragmentary view in side elevation, Fig. 3 is a cross section and Fig.4 is a detail.'-

A represents the axle, and 4B, B are the wheels. Connected to the axleare lcou lings 1, 1to which is secured the uprig t frame 2, andconnected to the frame 2 are bars 3, 3, which are bent inwardly at theirforward ends to receive a pole or tongue 4 to which they are secured.

Secured on the axle A, between the couplings 2, is a bevel-gear 5 andmeshing therewith is agear 6 secured on the shaft 7, which shaft is suported by a U-shaped hanger 8 having a hearing 9 formed at the centerthereof in which the shaft turns, and the hanger depends from bars 3',3. The shaft 7 has its forward end forked for 'the reception of a smallgear wheel 10, and the secondary Shaft 11, forward of shaft 7, has asimilar forked end 12 for a gear 13. The two shafts are connectedtogether by lplates 1'4, 14 whereby the two gear wheels 10 and 13 areheld in engagement thus producing a flexible connection. The rear end ofshaft 7 is journaled in a bearing 15 held in boxes 17 and 18 in thelower end of the V-shaped hanger 16 which latter is secured to frame 2.The shaft 11 is squared for a short distance as at 19, and rounded atthe end 20. Adjustable couplings are mounted on the squared portion ofthe shaft 11, and are secured to disks 21, 21, which are preferably madesemi-circular, and the disks are so arranged with respect to each otherthat they are on opposite sides of the shaft and one in advance of theother. 'lo the forward end of the shaft 11 is connected a rack-bar 22,and a strapiron 23 is secured to one of the bars 3 passin around the barto hold it slidably in a vertica position. A brace 24 extends from thisiron 23 to the tongue 4. Connected to the brace 24 is an arm 25, andthis arm carries one end of the shaft 26 which is journaled at its otherend in one of the bars 3, and on the shaft is mounted a gear 27 adaptedto engage the rack-bar 22, whereby the bar is moved u and down as thelever 28, which is connecteld to the shaft 26, is moved rearward orforward over the segment 29, thereby lifting the blades off the groundor lowering them for the cutting operation.

It will be seen that by having the disks semi-circular and one ofthemahead of the other, during their rotation they will cut out only theplants the blade of the disk strikes during its revolution. ln otherwords, the disk does not have a continuous cut, and by having the disksspaced apart, the plants bctween them areleft standlng.

It is evident that many slight changes might be made in the form andarrangement of the several parts described without departing from thespiritV and scope of our invention, and hence we do not wish to limitourselves to the exact construction herein set forth, but

Having fully described our invention and what we desire to secure byLetters Patent, 1s

1. In a cotton chopper the combination with a frame, axle and Yflexibleshaft, of semicircular disl-:s secured transversely on opposite sides ofthe shaft one in advance oi.' the other.

2. In a cotton chopper the combination with a frame, axle and. ilcxihlcshaft, of semicircular disks secured transversely on opposite sides ofthe shaft one in advance of the other, and means for raisingand-lowering' the Section of the shaft having the disks thereon, andmeans for locking said shaft in the position to which it is elevated.

3. In a cotton chonper, the combination with a frame, of an ax c, abevel-gear mounted on the axle, a flexible shaft, a gear on the fiexibleshaft adapted to engage the bevelgear, semi-circular disks mounted onthe shaft, a rack-bar connected to the shaft, and means for engaging therack-bar whereby the disks are raised andlowered.
